The present invention relates to receptacle lling devices, and more particularly to combined filling vand draining devices such, for instance, as are used to ll and drain the tubs of household clothes-washing machines.'

It has been proposed heretofore to `provide households with devices for filling and draining the tubs of clothes-washing maf chines. These devices usually comprise a T l@ having a lateral outlet to which a long liexible conduit, for conducting water to the tub, is connected. The bottom of the T is provided with a secondoutlet to which a short flexible conduit is connected. The other endof the L@ short conduit is attachable to a hot water faucet. The top of the T is provided with a third outlet, having a constriction therein, to which a tube attachable to a cold water faucet is connected. When the tube and the short conduit are connected, respectively, to the cold and hot water faucetsthe tub is lled with water which flows through the long conduit. When the short conduit is disconnected from the hot water faucet and the open end of the conduit is positioned in the sink the cold water is restricted by the entrance to the third outlet of the T to a jet which flows swiftly past the lateral outlet to which the long conduit is connected and out of the open 3o end of the short conduit. The velocity of the jet in passing the lateral outlet tends to draw air out of the long conduit, thus to produce a condition of unbalanced pressurebetweenthe water in the tub and the open end of the short conduit. This condition of unbalanced pressure causes the air on the surface of the water in the tub to push it up the long conduit and,Y

out of the open end of the short conduit into Y vthe sink. To start the Siphon action it is necessary to pinch or bend the short conduit for an instant. Many users of the device fail to pinch or bend the short conduit to start the siphon action and then complain that the device is defective.

The principal object of the present invention is to produce a combined filling and draining device in which the siphon action starts automatically.

To the accomplishment of this object and mi such others as may hereinafter appear, the

features of the present invention consist in certain devices, combinations and arrange-Y ments of parts fully described hereinafter Vand then pointed out'in the claims which possess advantages readily apparent to those skilled in the art. i

The various features ofthe present invention will be readily understoodfrom an inspection of the accompanying drawing illustrating the best form ofthe invention at present known to the inventor, in which,

Figure 1 is a View in elevation showing in full and construction lines, respectively, the device in use to ll and drain'a receptacle;

Fig. 4 'is a View in perspective of the baille.

ln the illustratedV embodiment of the invention the combined filling and draining device comprises a T 5 (Fig. V2) having three outlets 6, 7 and 8. Adjacent the outlet', the T 5 is shouldered to receiveone end of a long leX- ible conduit 9 (Fig. 1) the other end of which 75' extends into the receptacle or tub 10 to be filled and drained.V The conduit 9 is clamped to t-he T 5 by a metallic ferrule 11. Adjacent the outlet 8 the T 5 is shouldered to receive one endl of a short flexible conduit 12 the 80' other end of which is provided with an in` tegral roll 13 to permit the conduit'12 to fit over the smooth face of the hot water faucet 14 (Fig. 1). Theconduit 18 is clamped to the T 5 by a metallic ferrule 15. The third 857:7

outlet of the 'T5 is threaded to receive a threaded nipple Y16 whichis secured to one end of a short rubber tube 17- by a metallic ferrule 18. The other end of the tube is provided with a@ rolledend19.` Adjacent its rolled end 19the tube 17 is frusto-conical to enable itgto `be slipped tightly over` the shoulder onthe threaded end of ,a cold water faucet 20.v

ln order to make the end ofthe tube l17l 95 frusto-conical, after the tube is extruded theV open end thereofijs expanded before vulcanization by means of afrusto-conical plug V21 Y which remains in place during the vulcanization ofthe tube. By Ameans lof its -f-rusto-conical end the tube 17 may be coupled to faucets varying widely in diameter. l In many cases it may be desirable to use the device as a filler only. In such cases the tube 9 may be plugged or tied into a knot and either the rolled end 18 or the rolled end 19 may be coupled to the faucet 20, depending upon the size thereof. That is, if the faucet is large the rolled end 19 is coupled thereto. If the faucet 20 is small the ends may be reversed and the rolled end 13 coupled to the faucet. Y Y l l When used as a combined filler and drainer the device may be co-upled to the cold water faucet 20 with the long conduit 9 positioned in 15 the receptacle 10 and the short conduit 12 rolled into engagement with the hot water faucet 14. The receptacle may thus be illed with water having the proper temperature. To drain the receptacle the short conduit 12 29? is detached from the hot water faucet and the free end of the conduit is positioned in the sink 22. (Fig. 1). The cold water is then turned on. Velocity is imparted to the cold water by the restricted entrance 23 in the T 5. 25 f This restricted entrance converts the stream of cold water into a jet which travels centrally down through the T 5 and the conduit 12 leaving an annular space between the jet and the internal wall of theconduit. This space allows air to enter the open end of the conduit and flow into the conduit 9 thus maintaining a `condition of balanced pressure on the water in the tub 10 notwithstanding the tendency ofthe jet in passing the outlet 6 to draw air from the conduit 9.

In order to prevent the atmospheric air from passing up the conduit 12 to the conduit 9 the conduit 12 is provided with a baffle 24. As shown in Figs. 3 and 4 the baffle 24 is a 4.0.' hollow ferrule having on one end an inturned flange 25. With this construction the jet of water is free to flow centrally down the conduit 12, but the air entering the conduit 12 is prevented by the flange 25 from passing 4.5' beyond the baiiie 24. Thus the jet ofvwater in passing the outlet 6 is able to create a condition of unbalanced pressure between the water in the tub 10 and the open end of the conduit 12 to cause the expulsion of the water therefrom into the sink 22 under the influence of atmospheric air acting upon the water in the tub 1 integral meansfor connecting it to a faucet and means for preventing simultaneous flow of water and air therein -in opposite direce tions when its open end is positioned for draining. v

In a combined filler and drainer, a T having three outlets, one of which is restricted, a tube connected to the restricted outlet, two ieXible conduits connected, re spectively, to the other two outlets, a coupling for connecting the tube to a faucet, the shorter one of said conduits having a bafie insertable as a unit through its open end for preventing atmospheric air from entering the open end of the shorter conduit and {iowing to the longer one of said conduits. A

3. In a combined filler and drainer, a T

having three outlets, one of which is restricted, a tube connected to the Yrestricted outlet, two flexible conduits of dierent lengths connected, respectively, to theY other two outlets, a coupling for connecting the tube to a faucet, the shorter one of said conduits having a yhollow tube therein, said tube having an inturned flange on one open end thereof permitting water to 'pass' through the tube and out of the open end of the short conduit while'preventing air from passing up the short conduit into the long conduit.

In testimony whereof I have signed my name to this specification.

Because of the baille 24 the siphon action l will start as soon as the rolled end of the conduit 12 is uncoupled from the hot water faucet and positioned in the vsink 22. Thus it is no longer necessary-to pinch or bend the conduit 12 to initiate the Siphon action.

What is claimed as new, is:
